The compact RMI 422 robot mower will mow small to medium-sized lawns of up to approx. 800m? and is designed to do this in the shortest time possible, allowing you full access to your garden when you want it. As it is fully automated, once iMOW? is installed, it will mow, charge and adapt its schedule all by itself. If the robot mower battery runs low or it starts to rain, the RMI 422 will return itself to the docking station, and depending on how much of the lawn still needs to be cut, it will decide whether to charge itself quickly or slowly helping to conserve power.Fitted with a robust mulching blade, your grass will be finely shredded returning vital nutrients back into the soil. This also eliminates the need to dispose of any grass clippings. The iMOW? RMI 422 boasts 15 different cutting height settings, varying from 20mm-60mm so you can adjust it to suit you and your lawn! The RMI 422 comes with a 5-year extended domestic warranty (subject to registration and annual servicing).The STIHL iMOW? robotic mowers comply with all applicable safety standards. However, the iMOW? robotic mower is not a toy. During the iMOW? robotic mower’s active times, children, bystanders and animals must be kept out of the working area.Price shown excludes the supply of boundary wire, cramps, splicers and connectors which are required to either install or to operate the Automower. These items can be supplied alone or as a kit and are available separately.STIHL iMow’s must be installed by one of our trained technicians. Because of this, we can only service the local area to our stores. For more information please call us on 01302 756000.
